To all whom it may concern:

Be it known that I, LABS ANDERSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carbureters, of which the following is a specification.

This invention relates to improvements in carbureters for volatilizing or atomizing combustible liquids, such as gasolene, alcohol, kerosene, et cetera, and it has for one of its objects to provide improved means for auto! matically regulating the supply of gasolene at high and low speeds to suit the require ments of the speed of the engine or other devices to which the carbureter is connected.

A further object is to provide improved means `whereby the operation of the throttle will automatically and correspondingly ad just the needle supply valve.

A further object is to provide improved means for varying the adjustment of the needle valve.

A further object is to provide improved means whereby the float will control the height of liquid in the float chamber and which height may be varied b v the adjust nient of the float. j

A further object is to provide an improved atomizer nozzle.

A further object is to provide an improved device of this character which will be simple, durable and compa ctin construction in which ready access may be had to the parts and which is effective and eflicient in operation.

To the attainment of these` ends and the accomplishment of other new and useful objects, as will appear, the invention con` sists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings, illustrating an embodiment of the invention and in which- Figure 1 is a longitudinal sectional view of an improved device of this character constructed in accordance with the rinciples of this invention. Fig. 2 is a detail)top plan view with the cap removed. Figp is a detail sectional view on line 3-3 of Fig. 1. Fig. 4 is an enlarged detail view partly in section on line 4-4 of Fig. 2. Fig. 5 is an enlarged detail view of the air inlet opening.

Fig. 6 is a detail perspective viewrof the atomizer nolzzle. Fig. 7 is 'a detail perspective view of the adjustable member for regulating the movement of the needle valve. Fig. S is a detail sectional view on the line SMS of Fig. 2. Fig. 9 is an enlarged detail sectional view on line 9--9 of Fig. 2.

Referring more particularly to the drawings and in the present exemplification of the invention the numeral 10 designates a hous ing having an inlet port 11 in one side and an outlet port 12 in the other side, preferably arranged directly in line with the inlet port. The housing may be of any desired size and configuration and arranged at the center thereof is a cylindrical portion 13, which has communication with the inlet and outlet ports. A

Arranged within the cylindrical portion 1S is a throttle comprising two cylindrical members 14, 15, whichare respectively pro vided with a closed end 16, 17, and these cylindrical members 14, 15, are arranged concentrically with each other -with their closed extremities adjacent and spaced from each other and upon an upright axis. The cylindrical members are provided with openings '18, 19, 20, 21, which are adapted to register with each other in line with the inlet and outlet openings 11, 12. The open ends of the cylindrical members 111, 15, are adapted to rest upon the bottom 22 of thecylindrical portion 13.

Arranged inthe space between the closed ends 1G, 17, of the cylindrical members 14, l5, is a member designated generally by the reference numeral 23 (see Fig. 2) which is pivotally supported by one gend as at 24 to a fixed portion 25 of the housing 10. This member 28 is provided with a slot 26 extending longitudinally thereof adjacent the pivot 24 intowhich projects a depending pin or lug 27 which is supported by the closed extremity 17 of the cylindrical member 15. The member 23 is provided with a second elongated slot 2S adjacent the free end thereof to form a bifurcated extremity into which slot projects a pin or lug 29 which is supported by and extends upwardly from the closed end 16 of the cylindrical member 141` of the thrott1e so that when one of the cylindrical members of the throttle is axially rotated, the other cylindrical member will. be correspondingly axially rotated to vary the sizes of the openings 18, 19, 20-

and 21 in the sides thereof.

The members of the throttle may beadjusted by means of a cap 30, which is adapted to surround an upwardly projecting flange 31 on the top 25 of the housing, an

' ing. One of the stops, preferably the stop 37, is provided with an adjustable member 38 for varying the movement of the projection in one. direction and thereby limit the axial rotation of the cylindrical members of the throttle.

The housing 10 is provided with a chamber 39 which has an' inlet 40 through which latter the li id to be'vaporized enters the chamber and-the chamber may be provided witha clean-out plug in the bottom thereof. A valve seat 42 is provided in the inlet 40, with which coperates a sliding valve 43 mounted in a suitable support or bearing 44. A yoke 45 is provided which` is journaled 'to a suitable support 46 for pivotal movement and the arms of the yoke are adapted to engage in a recess 47 in the valve 43 for reciprocating the latter in it-s bearings to seat or unseat the valve as the yoke is moved.

Secured to the yoke 45 is a member 48 which extends 'into the chamber 39 and sef cured to this member 4,8 are ioats 49 which are preferably connected by means of a suitable connecting member 50, so that the ioats will stand on each side of the c lindrical portion 13 of the housing.

As the liquid rises in the chamber 39 the floats will rise and at the vsame time will cause the yoke to be rocked about its pivot by means of the member 48 to seat the valve 43 and thereby shut off the supply of liquid to the chamber. When the floats devscend-the yoke 45 will. be moved in the opposite direction to unseat the valve 43 to permitthe liquid to il'ow into the chamber. Arranged within the cylindrical portion 13-of thehousingand also extending into the throttle from the open ends thereof is a c lindrical member 51 which extends through t e bottoml 22, as at 52,ofthe cylindrical portion 13and'is provided with an opening -53`1ommunicating-with the chamber 39. The .'eyhndrical member 51' is provided with a valve seat 54 preferably adjacent the extremity 52 and a needle Valve 55 is arranged within the cylindrical member 51, which cooperates with the valve seat 54 to close the opening 5 3. The u per extremity 56 of the needle valve 55 pre erably projects through the closed ends 16, 17 of the throttle members lupwardly adjacent the ends of the member 63. The

worm members 69 are preferably arranged ranged withinl the space. between vthe closed ends 16, 17, of thet rottle members is providedwith Aa lateral'yenlarged portion 57 (see Fig. 2) having a slot 58 therein' and throughl rwhich the lextremityv ofthe needle valve 5,5 projects, the laterally alongated slot being provided to permit the throttle members to be axially rotated when the cap isrotated.

,Pivotally mounted intermediate its ends, within the cap 30, and upon the extremity and extends beyond the closed end 17 vand y into the cap 30. The'member 23 which is ar- 56 of the needle valve 55', is an arm or lever 59, one extremity of which latter is pivotally secured as at 60 to the cap, so that when the cap is rotated the armor lever 59 will be bodily rotated and the needle valve 56 will be axially rotated. The other extremity 61 of the armor lever 59 projects into an open slotted portion 62 in a member 63- which forms a Atrack or way. This member 63 is provided with` a laterally 64 which extends from the ace opposite to that in which the slot 62 is arranged, and

the housing 10 is provided with an upwardly projecting portion 65 having a slot 66 through which the stud 64 passes. The slot 66 is preferably elongated vertically and the extremity of the-stud 64 is provided with .screw threads 67 adapted to receive a n ut '68 forvholding the member 63 against displacement. As the cap,iand the arm or lever 59, are rotated, the extremity 61 of the latter will move within the slot 62.

roj ecting stud In order to automatically raise and lowerthe needle valve 55 to unseat or seat the saine with respect to the valve seat 54, the member 63 is adapted to be adjusted labout the stud 64 as an axis, which stud 64 is preferably located intermediate its ends, soV as to raisel and lower the respective ends of the member.

Any suitable means may be provided for. thus adjusting the member 63 and for this' purpose there maybe provided a pair lof worm members 69 which are gjournaled in a fixed portion of the housingfpreferably the projecting portion 65 thereof, and

horizontally and are'each provided with a cap .or projecting lug 70 arranged eccentrically withrelation thereto and these caps or eccentric lugs 70 arev adapted to project into suitable apertures or openings? 1 in the respective ends of the member 63 so that by axially rotating the worm members 69, the member 6 3 will be moved about the stud 64v as a pivot to raise and lower the respectivev ends thereof and thereby incline the track or way formed by the slot 62 in the member.

When the member 63 is thus adjusted it 'will be apparent that byl -imparting an axial rotation to the cap 30 and the needle valve 55, the. extremity 63 of, the arm or lever 59 will be moved in the inclined slot or way G2 and the needle valve will be raised or lowered according tothe direction ot rotation ot the cap or the .movement ot the extremity of the arm in the slot. By varying the angle of adjustment ot' the member G3. it. will be apparent that the degree of adjustment of the needle valve may be varied.

lt will also be apparent thatas the throttle members 14. 15, are adjusted to vary the supply ot' air, the needle valve will be simultaneously and automatically adjusted.

In order to adjust the member 63, suitable worm screws 7 2 may be provided which are preferably arranged to project beyond the top ot thecap, and each of the screws is provided with a knob or handle 7 3 by means ot which they may be rotated.

rl"he cylindrical member 51 which supports the needle valve 55 is provided with an externa-l peripheral shoulder 74 (see Fig. l) and an atomizernozzle designated `generally by the reference numeral 7 5 is provided with an aperture 76 extending therethrough intermedia-te the supply end T7 and the discharge end 78 of the nozzle. This nozzle 75 is preferably hollow to form a channel 79 (shown more clearly in vFigs. 1 and which communicates with the inlet and the discharge outlet. of the nozzle. The nozzle is adapted to be sleeved upon the tubular member 51A so as to engage and rest upon the shoulder 7l to be supported thereby, with the discharge end 78 thereof directed.A toward the out-let opening 12 ot the housing. A tubular member 80 is connected by one extremity to the inlet end 77 of the nozzle and extends through the inlet opening 11 of the housing. The free end ot the member 80 is supported by apartial closure `or grating 8l which is removably secured by means of suitable bolts or screws 82 to the inlet end 11 of the housing. This member 81 is preferably provided with a threaded extension 83 by means of which a suit-able p1pe may be connected to dlscharge a blast ot air'throligh the nozzle 7 5.

The discharge end of the nozzle ter-v minates wit-hin the inner cylindrical member 14- ot' the throttle, and an upright nozzle 84 is supported preferably by the bottom 2Q of the cylindrical portion 13 of the housing and communicates with a passage 85 in the housing, which pass-.ige has communication with the opening 'in the extremity 50 of the tubular member 51. This tubular member or nozzle 84 is arranged to extend transversely ot' the discharge end 78 ot the nozzle 75 and the free extremity of the member 84 terminates adjacent the end of the nozzle so that a blast of air fluid through the nozzle will be directed across the extremity of the tubular member 8l to create a suction therein, which will draw the liquid from the chamber 539, the liquid being discharged in the-form of vapor through the discharge outlet 'l2 of the housing.

The passage 83 preferably extends through the side. ot the housing and a. plug 8G may be provided which forms a closure tor the passage. lVhen the passage becomes clogged, theplug 86 may be removed to permit cleaning.

The wall ofthe cylindrical member 15 be` low the closedend 17 thereot'is provided with a slot 87 (see Fig 8) to permit the tree movement ofthe member' '15 with, respect to the member 23. i

lVith this improved con-struction it will be apparent that the degree of movement of the needle valve 55 may be' varied to any de# sired extent by adjusting the worm screws 72, without removing any ot' the parts of the mechanism. It will also be apparent that the supply of liquid may be varied at high or low speeds to suit the requirements of the speed of the engine.

ln order to prime the carbureter a member 88 may be provided in the form of a rod or bar which is adapted to extend-through the top 25 ot' the housing 10 so as to engage and rest upon one of the floats 49. This bar or member 88 is of such a length that when the lioats are normally in their highest position to close the inlet opening, one extremity thereof will project beyond the topA of the housing so that the operator may tap upon the extremity with his linger to vibrate the float to force a portion oit the liquid through the tubular member 84.
